The US is the only "developed" country where 10 are uninsured: https://en.wikipedia.org/wiki/List_of_countries_by_health_in...
Another N% are under insured, or hampered by high deductibles, copays, limits etc.
Whats the point of having a "high median net worth" if the basic needs of the people aren't met?
The US is including in their life expectancy data cases of stillbirths or nonviable fetuses at birth, which are not recorded in EU numbers, for example.
" measurement problems arise in international comparisons because the data are not consistently gathered or reported. Although the World Health Organization (WHO) has a formal definition of what should be included in the infant mortality statistics, anecdotal evidence suggests that countries do not use consistent practices in measuring these data (Haub and Yanagishita, 1991; Hartford, 1992).

The US is 22nd by median net wealth.
The average American has $432,000 in net assets, is the second richest in the world (behind Switzerland), and can trivially afford such an expense.
Did you mean that around 12-16% of the population can't afford an immediate out of pocket $400 expense? Because that's the real figure according to the Federal Reserve study that's constantly misquoted.
The median American has a higher net worth than either Germany or Sweden, and among the highest disposable income of any nation.
